Study the synthesis of LiBOB compounds using lithium sources from sea water

Indonesia as a country rich in natural resources has a source of lithium that can be used as raw material for making LiBOB salt. Natural sources of lithium are found in seawater or brines, mineral rocks and in geothermal fluids. Seawater contains large amounts of NaCl so that it is possible to have Na impurities in Lithium obtained from seawater. In this research, LiBOB synthesis has been done using a source of lithium-containing Na. LiBOB is made by solid-state reaction method, where the raw material is mixed in solid condition, then heating in the furnace for calcination and sintering process. Sample analysis was carried out by comparing the synthesis of LiBOB using lithium sources containing Na with LiBOB synthesis using lithium sources without containing Na. Based on the results of the XRD analysis, it is showed that the content of 3% Na in the Lithium source does not affect changes in the LiBOB crystal structure. FTIR analysis showed that the content of 3% Na does not affect the formed LiBOB functional group, even though there is a shift in wave numbers. The results of the thermal analysis showed that both samples occurred endothermic reactions and had a decomposition temperature of around 300°C. (paper)
